The Heil Sound RC 22 Screw-on Microphone Capsule features the same microphone element found in the Heil Sound PR 22 microphone. The screw-on capsule is intended for use with third-party handheld microphone transmitters that receive a 31.3mm / pitch 1.0mm connection. Some handheld transmitters feature a hexagonal-head set screw; simply loosen the screw to install the capsule. A three conductor contact circuit board makes contact with the transmitters output stage for maximum interchangeability.
